Mattheus slammed his right (pitching) hand into his locker after Sunday's game against San Diego. The fracture will not require surgery but because he won't be able to move his pitching hand, the work required to get his arm back in shape will force him to miss at least a month.

Duffy's return comes a bit earlier than expected, as the one-year anniversary of his surgery approaches June 13. The club was hoping for Duffy to go on a rehab assignment around that date, so his progress should be seen as positive. He will likely use most of the 30 days allowed for pitcher rehab assignments before he returns to the major leagues.

Happ suffered a nasty head injury in his last start May 7 against Tampa Bay, but his knee, tweaked as a result of the subsequent fall, continues to bother him. Happ won't be available until mid-July as a result of the move.

Nolin was scratched from Thursday's start at Buffalo in order to make Friday's game. The Blue Jays placed Darren Oliver on the 15-day disabled list and moved J.A. Happ to the 60-day disabled list to make room on the roster.

Nolin allowed just three runs (two earned) over 15 1/3 innings in his first three starts at Buffalo. He struck out 16 against just five walks. 

Oliver, 42, accrued a 3.18 ERA and 1.8 K/BB over 17 innings in the Blue Jays' bullpen. Oliver's disabled list stint can be backdated to May 18, and he's eligible to return by June 2.

Westbrook felt right elbow pain during a bullpen session Wednesday. The issue will keep him from coming back next week as originally planned, but it appears the issue will only push him back about a week at this point. Westbrook compiled a 1.62 ERA in 39 innings prior to the injury.

Carrasco has been dominant at Triple-A Columbus, as he owns a 1.36 ERA and 4.6 K/BB over seven starts (39 2/3 innings). The only hitch for the Indians is the eight-game suspension he was tagged with in April for hitting Kevin Youkilis with a pitch in his only major-league start of the year.

Carrasco has appealed the suspension. He may be able to come up for a start while MLB rules on the appeal -- likely July 10 against Toronto -- and then serve his appeal around the All-Star break, giving the Indians a chance to rearrange their rotation in such a way that Carrasco isn't just dead weight on the 25-man roster. 

However they decide to solve it, the Indians have been impressed with Carrasco's performance in the minor leagues, and they expect to find some way to bring him up this season.

Cabrera's .391 batting average and .701 slugging percentage lead all major-league players, and his .467 on-base percentage ranks second to Joey Votto. He's been hitless just twice in his last 34 games. He's the early favorite for 2013 AL MVP.

Willingham has hit .212/.368/.453 with eight home runs and 23 RBI in 171 plate appearances. His multi-homer performance was his first since July 24.
